Question 60086
I have to graph the exponential function:
 
y=-(3/2)^x

My table has the integers -2,-1,0,1,2
:
Just do what it says:
x = -2
y = -(3/2)^-2
:
a neg exponent indicates the reciprocal same as
y = - (2/3)^2
:
y = - (4/9)
:
in your table: x = -2; y = -(4/9)
:
:
Do the same when x = -1
y = -(3/2)^-1
:
Neg exponent, the reciprocal again
y = -(2/3)^1 or just y = = -(2/3)
:
in your table x = -1, y = -(2/3)
:
x = 0 is easy, any number ^0 is equal to 1
:
in your table x = 0; y = -1
:
:
x = +1
y = -(3/2)^1 is just y = -(3/2)
:
Let you do y = -(3/2)^2. Your graph should look like this:
{{{ graph( 300, 200, -4, 8, -10, 6, -(3/2)^x) }}}
